Sensors & actuators — inputs, outputs, and interfacing
Robotics workbook — outlines, parts, tools, wiring, and control next to the video.
Sensors
- Digital inputs (buttons, encoders) vs analog (some distance/light) — know your ADC resolution.
- Debouncing for mechanical switches; filtering for noisy lines.
Actuators
- DC motors need drivers that handle stall current; servos need appropriate voltage and current.
- PWM controls speed; encoders close the loop for distance/speed.
